A baby formed from filthy and/or dilapidated used condoms that inseminates an ovum in the grimy gutter or trash receptical in a major metropolitan area. The ovum is usually the result of 1 day or more old hooker vaginal secretions.

No two humans exist that could naturally spawn something as filthy as you; you must be a chud-baby.

A baby miraculously conceived through anal intercourse. The sperm, possibly through osmossis, makes its way to the baby-maker, where the fetus develops. The baby, then, travels back into the ass, where it is born through the butthole, presumably covered in shit.
